Other Parts Discussed in Thread: SN74LVC1G123, TPL5010

Hi,

Good day.

Our customer would like to know if we have a very low power operable pulse signal generator chip.
the frequency of the signal is pretty low (20-40Hz).

We would appreciate if you could point me to the correct product.

Thank you.


Regards,

Cedrick

    What exactly is meant with "pulse signal"? What are the desired inputs and outputs of the chip?

    The SN74LVC1G123 can generate a pulse; it expects a trigger signal, and the pulse length is set with R/C components.

    Hello you may also consider the TPL5010. It will generate a programmable periodic pulse. Normally it is used as a watchdog, if you use it "open loop" your period will be slightly increased by the reset time (tRSTn) of 320 ms. The period is set by a single external resistor.

    The TPL5010 is very low power, typical 35 nA.  maximum 50 nA.
